British Gas.
A nice man came out and told me my boiler is past it. I can spend £800 having it cleaned (and still need a new boiler soon) or get a new boiler. And he would sell me a new radiator to replace a dodgy one for £145.
So he made me an appointment with another bit of British Gas to have a quote for a new boiler. Second man told me that he had a special offer on a Baxi boiler which would cost ONLY £2700, but he couldn't do the radiator or anything else as that quote was only for JUST having the boiler replaced. So he gave me another quote for having the Baxi boiler with the radiator. £4200

, but he could knock £150 off for trading in the old one and £100 for something else and £200 off for it being a Tuesday etc and the cost would actually be £3600.
So the same boiler with the radiator is almost £1000 more than without the radiator.
Or I could have the radiator on its own for £189, and separately have the lower quote for the boiler , but it couldn't be done as one job.!!!
So I told him that British gas had quoted £145 for the radiator, and he suggested that I accept the quote for £145 for the radiator and £2700 for the boiler and ask to have them done at the same time.
At this point I felt like it was all a big con and started phoning around for a quote for the boiler from anyone other than British gas.
